Plyometric: Single-Leg Box Jump - Low Box

This movement optimizes Achilles tendon stiffness and promotes explosive power development, focusing on controlled landing mechanics.

Plyometrics (specifically low-impact, foundational exercises for power development) · Developed within performance strength and conditioning, drawing on principles from advanced athletic training. · To improve tendon stiffness, increase reactive strength, and enhance explosive lower body power, particularly beneficial for individuals returning to higher impact activities, or those seeking improved athletic performance. · Perform 3 sets of 5-8 repetitions per leg. Focus on strict form and soft landings. Rest 60-90 seconds between sets. This can be performed 1-2 times per week, allowing adequate recovery.

Why it works

The single-leg box jump introduces a rapid stretch-shortening cycle to the Achilles tendon and calf complex. Landing softly on a single leg demands precise eccentric control, strengthening the musculotendinous unit and improving its capacity to store and release elastic energy. The low box height minimizes impact, allowing for repetition and focus on technique without excessive joint load. This trains the nervous system to recruit muscle fibers quickly and efficiently for propulsive force.

How to practice

1. Stand about 6-12 inches in front of a low, stable box (e.g., 6-12 inches high).

2. Shift your weight onto one leg, keeping a slight bend in the knee.

3. Generate power by quickly dropping into a quarter squat on the standing leg, swinging your arms back.

4. Explosively drive upward and forward, using your arms to assist the jump, landing softly on the ball of your foot on the box with the same leg. Your knee should be stacked over your foot.

5. Control the landing, allowing a slight bend in the knee to absorb impact. Maintain balance.

6. Step down from the box and repeat on the same leg, or alternate as prescribed.
